EDWARD T. MALLOY, OF HAMILTON, OHIO.

SMOKE-HOUSE.

To all whom it may concern:

Be itknown that I, EDWARD T. MALLoY, a citizen of the United States,residing at Hamilton, Ohio, have invented a new and useful Improvementin Smoke-Houses, of which the following is a specification.

This application covers an apparatus of the general character of thatshown in my Patent No. 882,727, granted March 24, 1908.

My invention relates to improvements in smoke houses of the classadapted to use for the drying or curing of meat, fish or othersubstances, and the objects of my improvements are to economize floorspace; to provide means for moving and exposing the substances evenly tothe action of the heat and smoke for obtaining uniform results; toprovide ventilator controlled passages for changing the course of thesmoke as desired, and for heating the walls of thecuring chamber; toprovide means for attaching the substances to the endless carrier; toprovide means for automatically disengaging the driving mechanism fromthe chain shifter; to provide a supplemental heating chamber, and toprovide a compact and du rable construction and assemblage of parts forsecuring facility of operation and efliciency of action. These objectsare attained in the following described manner, as illustrated in theaccompanying drawings, in which Figure 1 is a longitudinal section of asmoke house embodying my improvements: Fig. 2, a front interior viewwith portions broken away; Fig. 3, a transverse section and Fig. 4 alongitudinal section of the chain shifter with an automatic clutchacti'lating device; Figs. 5 and 6 a side and an end elevationrespectively of a double supporting bar; Fig. 7, a plan with partsbroken away; Figs. 8 and 9 a plan and front elevation respectively ofthe angular ventilator plate.

In the drawings, 1 represents the end walls and 2 and 3 the front andrear walls of a rectangular structure of any desirable dimensions,inclosing a curing chamber 4 which may be closed at the top by means ofan ordinary sliding ventilator plate 5. The rear wall contains thechimney 6 and also a series of vertical smoke flues 7 which communicatetherewith near their lower ends through a dampered passage 8. A. slidingplate 9 serves to close the openings 11 formed near the top of the rearwall between the Specification of Letters Patent.

flues 7 and the curing chamber, and a sliding plate 12 serves to closethe top of said flues when desired. A sliding angular ventilator plate13 serves to alternately close the passages from the furnace 14 to thecuring chamber and to the lower end of the lines 7 in the ordinarymanner. The front wall is formed with a transverse opening 15. Aswinging shelf 17 hinged near the bottom of said opening may besupported therein on a fixed stop 18 as shown in Fig. 1. Sprocket wheels19 provided with depending endless chains 21 are mounted within the topportion of the curing chamber, and a vertical shaft 22 mounted on thefront wall may be driven simultaneously therewith by means of drivengear connections 23. Shafts 24 mounted within the end walls adjacent tothe opening 15 by means of open casings 25 are geared to a transverseshaft 26 which is journaled in the rear wall. One of said shafts 24 isgeared to clutch faced pinions 27 which are idly mounted on shaft 22 onopposite sides of a double clutch member 28 which is splined thereon.Nuts 29 provided with idle rollers 31 and threaded on the respectiveshafts 24 are thereby movable longitudinally within the casings 25. Abell crank lever 33 pivotally secured at a fixed point movably engagesat its respective ends with the clutch member 28 and with a sliding rod34 by means of washers 35 adjustably secured thereon. Pivoted trippinglevers 30 by contact with nuts 29 are actuated in opposite directionsalternately with the corresponding stop 35 for automatically moving therod 34 and the bell crank lever 33 with the clutch member 28 out ofengagement with the corresponding idle pinion 27 whereby the rotation ofthe shafts 24 is discontinued. Double supporting rods 36 are journaledat their ends in-depending housings 37 which are swiveled at oppositepoints on the respective chains 21. Each of said rods is provided witha, corresponding series of projecting pins or meat hooks 38 and withprojecting catches 39 near one end, adapted to detachably engage withthe latch lever 40 for preventing said rods from turning.

In operation, the lever 33 serves to actuate the clutch member 28 toengage the shafts 24 with the driven vertical shaft 22 for moving theidlers 31 with the front portion of the carrier adjacent to the opening15 in a forward direction. hen the chain reaches a predeterminedposition, said lever is automatically actuated by contact of the nutwith one of the tripping levers 30 for disengaging the clutch member 28.In this position of the carrier, the supporting rods are moreconveniently accessible for loading or unloading, after which the chainmay ,be'permitted to resume its normal depend- I 14 directly within thelower portion of the curing chamber 4 or to the fiues 7. The

'dampered passage 8 when open serves to admit the gases from the fines 7to the chimney for prevent-ing the over-heating of the rear Wall 3. hensaid dampered passage 8 to the chimney is closed the gases are permittedto ascend the fines 7 for heating the rear wall and thence escape whenthe top of said fiues are opened by the sliding of plate 12 fromthereover. By closing the top of said flues with the sliding plate 12and moving sliding plate 9 to uncover the passages 11 in the rear wallthe heat from said Hues may be admitted therethrough to the upperportion of the interior of the curing chamber 4. In this manner thegases or heat from the furnace may be directed as desired forcontrolling the temperature of the rear wall and also forheating eitherthe top or bottom portion of the curing chamber. After the curing of thecontents of said chamber is completed ventilator plate 5 serves touncover the top of the curing chamber for rapidly cooling andventilating its interior before the removal of its contents.

Having fully described my improvements,

what I claim as my invention and desire to secure by Letters Patent ofthe United States is 1. A smoke house comprising a curing chamber, asupplemental heating chamber supported within the curing chamber, andseparate means for heating said respective chambers.

2 A smoke house comprising a curing chamber, a furnace communicatingtherewith, a heating chamber inclosed within the curing chamber, gasburners therein, and pipe connections therewith from a source of fuelwithout the curing chamber.

8. A smoke house comprising a curing chamber, an endless carriertherein, a heating chamber supported within the curing chamber, gasburners therein and pipe connections for supplying gas to said burnersfrom Without the curing chamber.

4. A smoke house comprising a depending endless carrier, rotat-ivesupporting bars mounted thereon in pairs, and means for simultaneouslylooking or unlocking each pair of bars in relation to their rotativemovement.

5. The combination of driven wheels mounted at fixed points, an endlesscarrier depending therefrom, rotative supporting bars suspended in pairsfrom the carrier and provided with radial pins, and lever mechanism forlocking each pair of bars from rotating.

6. The combination of a driven endless carriercomprising rotat-ivesupporting bars depending in pairs therefrom, and means for preventingthe rotation of the bars.

7. A smoke house comprising a depending endless carrier, a screw adaptedto move a portion of the carrier laterally, clutch mechanism arranged toactuate the screw, and lever mechanism actuated by the screw forautomatically disengaging the clutch therefrom at predeterminedintervals in its movement.
